• General Description: Phenyldichlorosilane is an organosilicon compound that, under the conditions studied, demonstrated no reactivity when subjected to chlorination with phosphorus pentachloride, unlike other silanes and chlorosilanes. This resistance to reaction may be attributed to the presence of chlorine atoms on the silicon, which reduces its reactivity. The phenyl group attached to the silicon had little influence on the chlorination process, whereas methyl groups or oxygen atoms significantly altered the reaction kinetics. The compound's stability under these conditions highlights its distinct chemical behavior compared to more reactive silane derivatives.

Conversion of Arylsilanes, Arylchlorosilanes, and Siloxanes into Chlorosilanes

10.1039/j19700001641

The study investigates the conversion of various organosilicon compounds, including arylsilanes, arylchlorosilanes, and siloxanes, into chlorosilanes using phosphorus pentachloride. Thirteen chlorosilanes were successfully prepared with yields ranging from 78.1% to 96.4%. The study found that silicon atoms bearing chlorine or oxygen atoms were less reactive compared to other silanes. For instance, phenyldichlorosilane did not react under the given conditions. The presence of phenyl groups had a minimal effect on the ease of chlorination, while replacing phenyl groups with methyl groups increased the reaction rate. Oxygen attached to silicon significantly reduced the reaction rate. The study utilized infrared spectroscopy to monitor the progress of the reactions and confirmed the identities of the synthesized compounds through their physical constants and infrared spectra.
